An Oklahoma City man facing a murder charge told cops that he accidentally shot his wife while the couple was having sex and engaging "in sexual fantasy involving a gun."

Arthur Sedille, 23, called police last Tuesday to report that he "accidentally shot his wife in the head," according to a court filing. Rebecca Sedille, 50, died from a single gunshot wound to the head.

Sedille top cops that he and his wife "often engage in sexual fantasy involving a gun," and that he had "retrieved a handgun from a shelf beside the bed, racked the slide back causing the gun to cock and then placed the gun to his wife's head." The gun then discharged.

Sedille, pictured in the above mug shot, told investigators that he "did not realize the gun was loaded until the gun went off." He is being held without bond at the Oklahoma County jail.

On his Facebook page, Sedille's "likes and interests" include an assortment of pages devoted to weapons, gun sellers, and Smith & Wesson. He lists his employer as Stockton Telecom.
